1. Gases: Sound travels slowest in gases because the molecules are far apart and collisions happen less frequently.
* Example: Air (at 20°C): 343 m/s
2. Liquids: Molecules are closer together in liquids, leading to more frequent collisions and faster sound propagation.
* Example: Water (at 20°C): 1482 m/s
3. Solids: Molecules in solids are tightly packed, allowing sound to travel very quickly through vibrations.
* Example: Steel: 5960 m/s
Key Points:
* Temperature: Sound speed generally increases with temperature in all media.
* Density: Denser materials tend to have faster sound speeds.
* Elasticity: Materials that are more easily deformed (more elastic) also tend to have faster sound speeds.
